1 Claim.

This invention relates to improvements in can opening devices and more particularly to a means for effecting provide a simple, eflicient removing means for a er or other container, manually opene and without causing erator.

Another object of conventional enabling a person and inexpensive lid can or other food containwhereby the can may be d in the minimum length of time traumatic injury to the opthis invention is to provide a can with self-contained means for quickly remove the top or bottom thereof without the use of extraneous means such as a a key. I

A further object of a can with a removable top so designed and shaped the lid to be the can as to r that the top may and become separated therefrom time.

tool, and without employing even this invention is to provide be lifted out of contact er object of this invention is to provide a wire so anchored and seated between removed and the adjacent parts of as to be separated fro eadily to be readily and uniformly be dislodged manually so m the can to permit the lid removed from the can to open the latter. Another important to secure the lid upon the opening of a can so as to close the lid may be quic the simple act of disengaging a same in such kly and effectively pried loose by object of this invention is a manner that the wire that binds the lid frictionally in anchored relation in the can.

A still further obj is to provide be closed by cent section of nular bead, both seam of the ct which has A wire is lodged lid and ect of the present invention can with an annular top or botd having an opening designed to The lid and adjacan in opposing directions in such a manner as to provide an annular socka slit opening thereout at the top.

in this socket so that its major diameter is anchored and seated in the socket and its minor diameter projects out of the slit where n the wire extends. By means of a terminal 0 the press fit the lid, the wire i when the operator,

removing the lid, will grasp nal and by between exerting both beads of can and of s pressed into position so that desiring to open the can by hold of the termia uniform pull upon the wire to lift it out of the socket he will, due to the being designated wedging action exerted by the wire, readily lift the lid out of the opening of the can, at the same ime.

With the above and other objects in view my invention consists in the combination, arrangement and details of construction disclosed in the drawing and specification, in which similar reference characters designate similar parts in the several views of the drawing.

In the drawing,

.Figure 1 is a vertical sectional elevation of my invention,

Figure 2 is a top plan View thereof,

Figure 3 is a fragmental detail side view of a can showing the outer bead of the can,

Figure 4 is a cross-sectional view of a can showing the lid wire-bound thereupon to close the opening thereof, and

Figure 5 is a fragmental sectional cross view showing the lid unseated from the fixed bead 20 on the can and from the wire.

In the drawing, which is merely illustrative of my invention l0 generally designates any can, container or vessel made from any desirable material such as metal, paper, cardboard or other 25 material desired. The inside or interior of the can is designated H, the bottom is designated l2, the bottom bead of annular formation upon the can l3 in which the bottom is clinched securely to close this end of the can or container. The annular flange M of the bottom I2 is the part that extends into the bead l3 before both parts are pressed tightly together in the conventional manner.

The can also has, at its opposite end, another annular bead designated IS in which the flange ll of an annular member or top portion I! is contained before this flange and this head are clinched together operatively. This annular member provides in effect an internal flange upon the interior ll of the can extending at right angles to the axis of the cap.

The lid I8 is in the form of a disk of metal preferably or of any other suitable material. This disk is made of a size and diameter sufficient to 45 make it snugly fit the opening A provided in the can by the annular flange or top portion Hi. The outer circumferential edge of the disk is designed, when the lid accurately fits the mentioned opening, to flt the outer circumferential edge of the flange is. I provide the out-er circumferential edge of the flange l6 with a fixed annular bight M which continues around and back over the marginal portion of the flange and assumes the shape of an annular bead which is concave and 55.

be crimped and pinched ti 4, 'into the socket formed by both than 360 degrees, so that thereby the top of the socket forms a slit or provides an annular open portion; The meeting e ges of both bights M the flange will beins'erted into the fixed annular bead 19 of the flange.

The wire 25 is shaped into a coil, and this coil is anchored and seated upon the bead l9, so that the head 26 of the lid when the lid is mounted so that its side portion engages the Wire, and so that its bight N is in line with the bight M of the flange and the base portion of the lid is in line with the flange is.

This having been done the beads I 9 and 20 will gl tly together against the opposing diametrical so that the circumferential edge or top edge 23 of the bead 2e engages above the half section of the wire, to securely anchor the wire beads. Before thus anchored between the beads I the meeting edges 2| and coat the inner faces of the beads i9 and 28 a slight distance, to provide the sealing material or lining 2}. The wire has one end of its split coil cemented is made into a ring will be in alignment and the opening of the can closed, and that a fluid tight seal and connection will exist between the flange, and lid excluding air from the interior of the can.

In operation the user takes hold of the hand 5 by the claim.

What I desire to claim and secure by Letters Patent iSIra- A tin can having a marginal hook-shaped bead at its top with an annular channel flanking the bent upwardly so as to project into said annular channel in clinched relationship, a cap having a flange formed concave-convex in cross-section 60.
